They had some cool looking bmwider decks bur they were all sold out 2hrs after he posted about em on Instagram.
If I read the descriptions correctly, many of them are miscuts, but maybe not all... anyway, nothing bigger than an 8.38 last I checked.
Yes, but a couple of those bigger boards with longer wheelbases would have been good for you to drill in from the tail end, which would give you a shorter wheelbase and longer tail.
I know that can cause other issues (too many fingers of flat) but as it is sold out, I guess you will never know.
A couple of other decks that had long wheelbases at the expense of a shortened tail worked well though, when drilled in 3/8" using an old 6 hole baseplate, so it would be more a case by case basis for what would work well and what might not.
The best way to test that would be use the six hole baseplate in the last two holes through the existing holes and stand on it when set up and just see if the manual point on the tail works. If yes, drill it in, but if no, then at least you didn't waste time drilling it when you didn't have to.
I guess this is all based on having a six hole baseplate handy too, eg any old baseplate including no names, or any Indy 159 and up in standards will work.
